////////////////////////// THE INDUSTRIAL AUTOMATION SECTOR IS NOW BEGINNING TO DEMAND SOLUTIONS THAT WILL HELP IT TRANSITION AND BENEFIT FROM A MORE CONNECTED WORLD. plants. Making wholesale changes to those systems is both very expensive and risky so understandably, operators are reluctant to tackle that without the right reassurances from their suppliers. But if it isn’t broken, why do we need to fix it? Supporting legacy ICS features is challenging for manufacturers and increasingly, the suppliers of those systems. Many of these systems are now 20+ years old, so maintaining them becomes more difficult as the in-house expertise disappears, or replacement parts become unavailable. The adage, ‘if it isn’t broken, don’t fix it’ really doesn’t apply in a scenario where, sooner or later, something will break and fixing it may not be possible. Is this just a maintenance issue? Absolutely not, maintenance is part of the problem, but the real issue is the lost opportunity to increase efficiency and productivity through the adoption of new technologies. Older systems are often bespoke and less likely to be compatible with the new equipment or production processes. This goes beyond efficiency to include safety; many processes may not be well supported and modifications, upgrades or patches may not be documented at all. INTELLIGENTCIO 43
